Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes
Chemistry – A European Journal, EarlyView.Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media
Chemistry – A European Journal, EarlyView.This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

Synthesis of Group IVB Metals Oxicarbides by Carboreduction Reactions
Materials Research, 2002 The metals of the group IV B (Ti, Zr, Hf) present a series of carbides and oxicarbides with scientific and technological interest. Many of these compounds belong to the subsystem "MO - MC" of the pseudoternary "MO - MN - MC" system (where M = Ti, Zr or ...

[Ti(py)4I2] as an Entry Point to Titanium(II) Chemistry via Titanium Metal Oxidation
Chemistry – A European Journal, EarlyView.A strategically novel approach based on the oxidation of Ti metal enables access to Ti(II) chemistry. Controlled formation and complexation of Ti diiodide affords the Ti(II) complex [Ti(py)4I2], which serves as a convenient entry point to Ti(II) compounds.
